The SC61 can't be done in a T4 .63 A/R. It can be done in a tangential T4 .58, .68 or .81 A/R though. Here is a T4 SC61 .81 A/R I sold a while back. Sorry for the blurry picture.

My power goal is 465whp but I really want to run an 11.3 so whatever it takes 
I'm going with a Precision SC61 T3/T04E 69 trim. Still debating on the A/R. I would like to go with the .48 to see what it can do but ...

They probably can now but allot has changed at Precision. The last I heard (from Rod Short) is they could only do .58 .68 and .81 Sorry for the misinformation if they can do .63 A/R in the 61 T4. I will find out tomorrow (for myself too).

Did you mean a T4 69 trim turbine wheel? Or, the T3 69 trim (aka Stage 2 from Turbonetics) turbine wheel?

Uses the new GT35R compressor. Choice of compressor housings is the TO4E (3" in / 2" out) or the TS04 (4" in / 2.5" out).
The exhaust side can be either the T31 69 trim, T31 76 trim, T350, or T4 69 trim turbines. Exhaust housings can be either 0.48 or 0.63 A/R with 4 or 5 bolt turbine discharge sides with or without internal gate provisions.

i know the box in the pics says garrett, but iirc, precision turboes are not made by garrett correct? just curious because i know that with garrett units, the 4 bolt housings are better than the ford style 5 bolt housings, but i hear alot of honda guys have to use 5 bolt housings when keeping a/c or something of that sort, right? i would like to see if there is any flow changes with the precision 4 and 5 bolt housings (of the same type - e.g. 4b T3 vs. 5b T3 with same wheels)
